I live in New York City and often find myself riding at night. Most areas of NYC are as bright at night as they are during the day, there are some areas that get pretty dark. As such I'd like to invest in a headlight, but I don't want to spend too much money since it's not something I'll need everyday. Does anyone have any strong opinions about the Nighthawk Raptor 10w? It's on sale at performance bike for $40, which makes it quite attractive, and I doubt I'd need anything stronger than 10w in NYC anyway.
